Detail

The design features large reptilian creatures with only two long forelimbs and no hindlimbs, as well as long, prehensile, serpentine tails. Several aspects of their appearance are noticeably skeletal, particularly their torsos and their heads.

Their heads closely resemble those of Mosasaurs such as Tylosaurus, and their jaws possess two rows of serrated, razor-sharp teeth. The Skullcrawlers have four digits in total of each hand, with the thumb being the smallest digit and the rest of the digits being larger and of the same size, and a bony spike protrudes out of each elbow.

Additionally, they have long, prehensile triple-forked tongues that they can use to grab their prey. Behind their skull-like heads, lie their eyes, small and like that of a lizard. Their eyes have horizontally-slitted pupils, similar to those of a goat.
